An image forming apparatus may generally utilize a number of devices to transfer and deliver an image forming substance, such as toner, to the image developing system. Often these devices may be located within a toner cartridge, however, this is not always the case. A toner sump or reservoir may be used in an image forming device to retain toner until it is required by the developer system. The image forming substance may be transferred from the sump or reservoir using a series of component rollers, which may ultimately transfer the image forming substance to the image developer system. When the transfer of image forming substance in the image forming apparatus is relatively poor, and inadequate image forming substance is delivered to the image development system, a phenomenon called starvation may occur which may then yield an irregular printing pattern.
